### 5 SQL Queries That Popularly Used in Data Analysis

Here are five popular SQL queries frequently used in data analysis. 1. SELECT with Aggregations Summarize data by calculating aggregates like counts, sums, averages, etc. SELECT department, COUNT(*) as employee_count, AVG(salary) as average_salary FROM employees GROUP BY department; 2. JOIN Operations  Combine data from multiple tables based on a related column. SELECT e.employee_id, e.name, d.department_name FROM employees e JOIN departments d ON e.department_id = d.department_id; 3. WHERE Clause for Filtering Filter records based on specified conditions. SELECT * FROM sales WHERE sale_date BETWEEN '2024-01-01' AND '2024-12-31'   AND amount > 1000; 4. ORDER BY Clause for Sorting Sort results in ascending or descending order based on one or more columns. SELECT product_name, price FROM products ORDER BY price DESC; 5. GROUP BY with HAVING Clause Group records and apply conditions to the aggregated results. SELECT department, SUM(salary) as total_salaries FROM employ

# How to Fix datetime Import Error in Python Quickly

Here's a quick resolution for import datetime Python error. The reason is your .py python script name and datetime are the same. I'll show you how this error happens and its resolution.

## Here's the Resolution for ImportError

I've created a script called 'datetime.py.' to check whether the minute value is 'odd' or not. During the import of my python script, I got the import error cannot import name datetime.

My Script: datetime.py

My script's intention is to find whether the minute value is odd or not.

### Python Logic

```from datetime import datetime
odds = [ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19,
21, 23, 25, 27, 29, 31, 33, 35, 37, 39,
41, 43, 45, 47, 49, 51, 53, 55, 57, 59 ]
right_this_minute = datetime.today().minute
if right_this_minute in odds:
print("This minute seems a little odd.")
else:
print("Not an odd minute.")
```

### ImportError

I have imported my datetime.py from Linux. It gives an error "ImportError: cannot import name 'datetime' from partially initialized module'.

The reason for the error is the .py module name and Python package name both are the same.

Resolution

I've renamed the .py module and imported it to Python3. Then, the import is successful.
